That is a swirl control valve code. The swirl control valve is on the intake manifold and unfortunately the only way to get the valve is to replace the entire intake assembly, it is not available seperately @ this time. You will have to purchase this and the gasket from you Nissan dealer. Hope this helps.

Engine check light keeps burning


Black smoke is to much fuel. Have the codes read. Driving it like this will burn out the catalyst system. Not a cheap fix.

Engine light on, p1138 car shakes when i waiting for in a red light


Hello, Since you have a Code number, either you or someone else must have used a scanner to get it. Nissan calls this a "Swirl Control Valve" which I beleive is fancy for EGR. The valve itself may be bad or the communications to that Egr valve may be bad from the PCM.

Clean the soot out of the EGR passage and have the valve tested. The Code has also been shown to represent an O2 problem on that same car, just depends on the source you believe.

You can get free scans at Autozone, Oreilys, and Advance autoparts. Sorry for the delay in response, but when anyone in the house uses my PC mail program Fixya is activated and I am not active.

The service engine soon light came on. I went to auto zone and they found trouble code P1456. How do I fix this?


hi, dear friend, this is an obd2 trouble code table. it can help you understand the meaning of code.
The best way to fix a P1456 error (small evap. leak) on your Nissan is to have a "smoke machine" test done on it. This machine is hooked up to your car and pushes smoke throught the evap. system. The smoke will shoot out of the leak and indicate its precise location. You can also try getting a new gas cap and make sure that it clicks 3 times when you close it after filling your tank. Also, NEVER leave your car running when your fueling up as this can cause your "service engine soon" light to come on. The best choice however is doing the smoke test as this will elimiate any guess as to the location of the leak. Nissan dealers can perform this smoke machine test for you for about $90.00 and can save you alot of money by pin-pointing the leak so you don't keep buying parts you don't need.

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

Check engine lite came on i hooked up to the computer on the car and the code P1138 came up came up can you tell me what this means.


On the Nissan it indicates that the 'swirl control valve' is malfunctioning. The valve is located in the lower part of the intake manifold. Removing and cleaning the valve sometimes provides a solution to the problem.

2002 Nissan Sentra Check engine light diagnostics


There is a leak somewhere in the evaporative emission control system. The best way to test that is have a smoke test done on it to find out where the leak is. You'll have to call around to see if any repair shops have a smoke machine, or call a dealer.
